What We Do
What We Do
At the Department of Water Resources (DWR), we know water. Every day, we produce more than 70 million gallons of water to be used by the residents and businesses of Gwinnett County.
We have invested nearly $1 billion over the last two decades to ensure that the water we process and later return to the environment is among the highest quality in the country.
DWR provides safe, clean water for nearly one million residents of Gwinnett County, as well as sustainable protection of local waterbodies.
We also conduct extensive water-related research to inform our current processes and prepare for the future.
Lake Lanier, our sole water source, supports our quality of life in Gwinnett County and water conservation can help sustain this vital resource. Learn more
Our two drinking water facilities provide safe, reliable drinking water from Lake Lanier that is delivered to homes, businesses, and other facilities via nearly 4,000 miles of distribution pipes.
More than 3,000 miles of sewer pipelines deliver wastewater to our three wastewater treatment facilities, where water is treated with some of the most technologically advanced treatment processes in the country.
We manage more than 1,400 miles of stormwater drainage pipes across the county to safely convey stormwater runoff from streets and private property to streams, rivers, and lakes.
We oversee construction projects to update and maintain the county’s water, stormwater, and sewer systems, along with our water production and wastewater facilities.
As an industry leader in water-related research, we partner with local universities, national research organizations, and international experts to conduct research and proactively address challenges.
The Water Tower at Gwinnett was conceived to guide policy makers and become an international innovation hub for water research. It is expected to be open to the public in 2021.
We frequently conduct projects to proactively maintain our water, sewer, and stormwater systems and ensure public health.
